My little corner of the internet that I've made into a hodgepodge of rants, batties, bunnies, lovely ladies, gorgeous gentlemen, spectacular scenery, graveyards, and skulls. And baked goods. So many baked goods.

The James Webb Space Telescope has just completed a successful first year of science. Let’s celebrate by seeing the birth of Sun-like stars in this brand-new image from the Webb telescope!
This is a small star-forming region in the Rho Ophiuchi cloud complex. At 390 light-years away, it’s the closest star-forming region to Earth. There are around 50 young stars here, all of them similar in mass to the Sun, or smaller. The darkest areas are the densest, where thick dust cocoons still-forming protostars. Huge red bipolar jets of molecular hydrogen dominate the image, appearing horizontally across the upper third and vertically on the right. These occur when a star first bursts through its natal envelope of cosmic dust, shooting out a pair of opposing jets into space like a newborn first stretching her arms out into the world. In contrast, the star S1 has carved out a glowing cave of dust in the lower half of the image. It is the only star in the image that is significantly more massive than the Sun.
Thanks to Webb’s sensitive instruments, we get to witness moments like this at the beginning of a star’s life. One year in, Webb’s science mission is only just getting started. The second year of observations has already been selected, with plans to build on an exciting first year that exceeded expectations. Here’s to many more years of scientific discovery with Webb.
Our solar system has 4 inner rocky planets: Mercury, Venus, Earth and Mars; and 4 outer gas giants: Jupiter, Saturn, Uranus and Neptune.
This is all well and good until scientists realised it’s not the norm at all.
Most solar systems have 1 or 2 super sized rocky planets orbiting their star well outside the Goldilocks Zone, and they mainly have toxic atmospheres inhospitable to any life.
So what happened to let us have 4 inner rocky planets of such small size?
This fucker right here:
Jupiter was the first planet created in our solar system, and it’s a beast of a planet. It can fit 1300 Earth’s into its size.
Now, by itself, Jupiter was greatly affected by the Sun’s gravitational pull and it slowly began heading inwards from its spot in the outer solar system.
As it moved forward, it dislodged most of the debris that was forming. Ceres, a dwarf planet located in the asteroid belt between Mars and Jupiter, was a core of a forming planet that Jupiter interrupted.
This disruption stopped larger debris forming into 1 or 2 super planets, and pulled the debris apart from each other.
So, what stopped Jupiter from gliding through everything and ceasing any formations?
Saturn.
Saturn formed and due to its location and orbit around the Sun, it created a drag on Jupiter, halting its journey forward. This drag and pull between them eventually caused both planets to retreat into the positions they are today.
Jupiter’s warpath forward is seen in the remains of the asteroid belt, planetary debris never allowed to form.
And what remained pulled into the 4 planets we know today.
The Solar System is so strange, and I love it.
By the way, what this post describes is known to science as the Nice model, and some versions of it include Jupiter throwing a third ice giant planet out of the Solar System altogether.

i think there’s some theories that Jupiter is a failed star
Yes and no. But I love that you brought this up.
In order to become a star like our Sun (a main sequence star) Jupiter would need to become approximately 1000 times its own current mass.
However, it would need only 13 times its current mass to become a brown dwarf.
So, because Jupiter is made of hydrogen, it theoretically could become a star. But it was never failed at its current size. Unless 13 more Jupiter’s collide with it.
Being nice to someone you don’t like is not manipulation btw it’s being civil
Mmm no, this is like seeking validation. Ofc it’s best to be nice but if I don’t like you or we both dislike eachother, then there’s no reason for us to communicate or be around eachother. It’s not about being immature, I would much rather not put myself in such a situation.
I love the x-men so much because that’s just what leftist infighting is like! that’s literally all it is! xavier is a sellout and they all hate him but he’s the only one with any money. everyone complains about “they keep switching sides and dating each other it’s so fucking confusing” like my dudes have you never been a part of any socialist organisation, ever. then people will go “magneto is so strong how has he not killed a bunch of teenagers” HE DOESN’T WANT TO KILL THEM! this started in a goddam basement over coffee he does not want to hurt them he just wants them to shut up and listen and will fling cars to do so
This probably sounds obvious, but I learned today that prisoners aren’t protected by OSHA regulations, and that this is another reason why employers are so eager to utilize this modern slavery. It’s only a couple cents an hour, less transportation costs than the overseas sweatshops, and if you want people to work with hazardous materials without proper training? That’s fine too! Prison labor is the ultimate free market solution!
If you want to really change the world, prisoner rights and prison reform is the way to go. Removing the ability of the ruling class to effectively punish the population frees everyone to challenge them in meaningful ways. Arbitrary violence and incarceration is how they keep people scared and divided. There is no crime in our society that isn’t generated by our society. Even the worst ones you can think of.
Prisoner rights are human rights. Prison abolition is mass freedom.
